Water scarcity is the lack of freshwater resources to meet a particular region's standard water demand for humans and nature. There are two types of water scarcity: physical and economic. Physical water scarcity is where there is not enough clean water to meet the demands of nature in the area, including that needed for ecosystems to function effectively, such as rivers and ponds. Countries such as Central and West Asia, which caused a lack of fresh water underground, and most of Africa (mainly North Africa) and some parts of the West, such as California, often suffer from droughts. Another type is Economic water scarcity. Economic water scarcity is the most common due to the daily high demand for fresh, clean water from humans to complete their daily routines. This type of water scarcity is caused by a lack of investment in infrastructures, as well as inequitable distribution that draws water from rivers, aquifers, and other water sources. Other crucial roles in water scarcity are climate change and insufficient human capacity.
